Since this appears to be a fairly new list, I assume it is for Scammers-in-Training. They probably still wet the bed at night. They eat Kowdunga for breakfast. (Kowdunga is a colloquial term for sacred, white cow shφ.)  But I do for them what I do for real professional scammers. Never answer the phone even if it shows your area code, or more recently, your own phone number and/or your name! That is one of their latest spoofing tricks. (My answering machine does ask for a message to be left, but they never leave a live one.) Never call back because that could cost you money and/or tells them when you are home. Block the number. Get yourself a Panasonic phone system that blocks 250 numbers. A system with 3 handsets is about $100. Check Amazon.com for one. A nice feature is when the àѕѕηθļєs call back, there is no ring to irritate you.
